M
starts withThe smallest species of the genus, the length of their head and body combined is 300 to 350 millimetres and they weigh a relatively light 950 to 1400 grams. The hindfoot is 80 to 92 mm.The tail is 265 to 390 mm, a tawny colour with back flecking, and distinguished by dark brown tufted hair that begins two thirds along its length.The ears are 30 to 33 mm from base to tip, very short for the genus, the eyes are large and black.The upper-side of the pelage is an olive-buff colour, deep in tone and marbled in appearance.The fore part of the head is a deeper reddish brown, becoming paler at the cheek, a similar colour is found across the upper limb. The ventral side, up to the chin, is pale to whitish and may have a yellowish tone at the belly.
The behaviour of P. burbidgei is shy. They are mostly active during the night and able to relocate with quick and adept movements.
The distribution range is restricted to high rainfall locations, with 1,200 to 1,400 mm of precipitation annually, at the coast and islands of the Kimberley region. The population occurs commonly at the few known locations, including the islands Bigge, Boongaree and Katers, where the first specimens were obtained in the 1970s. They are associated with habitat occurring on King Leopold sandstone formations; the vegetation is open woodland of eucalypts and Owenia vernicosa.
The species is present in the Charnley River–Artesian Range Wildlife Sanctuary in the Kimberley region of WA.
The species retires to caves or other cavities amongst the sandstone. The diet is primarily composed of grasses and ferns.The breeding period is assumed to be year-round, with most births occurring during the northern wet season.Petrogale burbidgei is listed as near threatened, partly because of the small size of its known range.
